I've used SPD's for years but elected to install the Keo 2 Max's on my new carbon bike. I can't believe how difficult it is to break them loose.
They're factory adjusted to the lowest pressure setting but I have to do a major high torque heal twist (to the outside) to get them to release. I have the greys on my Sidi's so I put red's on my other shoes but the red's are even harder to release. Defect or perhaps a break in period?
If you are comparing the feel of a Look Keo to a spd pedal I can understand your concern. The effort to release is entirely different especially considering the Look has a fixed front mounting point so you can't toe out at all.
You mentioned factory adjusted. If you hanven't tried get a hex wrench on the pedal and turn counter clockwise to see if the tension can be released some.
